@3run: thank you for your help. It is appreciated.
As much as I knew that, I still had to try and exhaust all options before getting to the final conclusion. -- On the offchance that someone pointed me in the correct direction for such a thing (If it was even possible, though I knew it likely 98% wasn't) I would have been happy with that as well.

Any chance someone knows why grab_screen2 Doesn't work with on_z?
